Question

find the zeroes of the polynomial 4x square-5+x​

Answer 1

$\sf\small\red{Given:-}$

• $. {4x}^{2} - 5 + x$

$\sf\small\red{Find:-}$

• Zero of the polynomial .

$\sf\small\red{Solution:-}$

a and b are the zeroes of 4x^2–5x+1=0…..(1)

a+b=5/4……………(2)

a.b=1/4………………(3)

Multiply eq.(2) and eq.(3)

a.b.(a+b)=5/4×1/4

a^2.b+a.b^2=5/16 .
